Abstract

Recent advances in extraction technologies have increased the amount of nonfloating oil being shipped worldwide. When nonfloating oil is released on water, it is difficult to track and locate as there are no proven detection nor containment methods for either oil suspended in the water column or deposited on the seafloor. This article describes a method to detect oil in the water column which assists response personnel with information on where ideally their response efforts should be focused. The system is designed to be left in place for an extended period of time without the need for manual inspection as is the procedure currently in place when snare sentinels are used. By using the proposed systems, the overall time of personnel in the field can be decreased and at the same time increase the amount of information provided so that informed decisions can be made.

Description of the Invention

The components of the system include a motor-driven pulley, oleophilic snares and line, a surface buoy, and an optical, non-contact UV filter-fluorometer sensor (Figure 1).  The system is suited for deployment in a river or estuarine environment but can be used in open water as well.  Once deployed the system can be programmed to engage the pulley which would draw the oleophilic snares past the surface-mounted UV sensor.  Each snare’s position on the snare line is known so that as the line is drawn up past the...
